All the experiments were conducted on a PC equipped with a 2.4GHz Intel Core™ i7-8700T, with 12 cores and 8 GB of RAM, running Ubuntu 18.04.3. We used SCIP 6.0.2 [1]} as the ILP solver and Gurobi 8.1.1 [2]} as the LP solver. Since the ILP-HEURISTIC does not need column generation, we used Gurobi as the ILP solver for this heuristic.
